ELECTRICAL IGNITION APPARATUS.

Specification of Letters Patent.

Patented June 29, 1909.

Application filed January 25, 1908. Serial No. 412,537.

To all whom it may concern:

Be it known that I, TnEoDoRE HUBERT, a citizen of the United States, and resident of New York city, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Electrical Ignition Apparatus, of which the following is a specification.

The object of my invention is to provide improved means for producing sparks in the cylinders of explosion engines, and particularly to cause accurate tiring in the cylinders at the required. time, and my invention is especiallyv applicable for use in multiple cylinder gas engines of high speed.

Attempts have been made to utilize an induction coil for each engine cylinder in connection with a single vibrator for all the coils for causing the make and break of the circuit for each coil. In such ignition systems, as known to me, the difliculty experienced is that .they introduce inductancc and destroy or retard the desired effect, thereby making thc device slow in action, because ot the introduction in the circuit of au extra highly inductive element, such as the winding or windings of the magnet of the single vibrator. In my invention I utilize an induction coil for each cylinder orP the engine, and in circuit therewith I utilize a sin le vibrator device having my .improved dlouble wound magnet, wherein a plurality of cores each having a winding, which windings are substantially equal inn umher of turns and ol substantially the same gage of wire, and said windings are wound in opposite directions and are connected in multiple with respect to A cach other, and each such winding 1s in series in the circuit with the corresponding induction coils of the engine, whereby the current traversing the circuit at any time splits or dividesat said windings of the vibrator magnet and thereby reduces inductance in said vibrator' windings. Such magnet operstes the vibrator' to make and break the circuit ot the primaries of the induction coils. In order to reduce an self induction in the magnet coils due to the make and break of the armature circuit by the armature or vibrator, I denser bri( ged across between the windings Or the terminals of the windings of thc vibraf tor magnet. A condenser' may also be used bridged across the make and break contacts of the vibrator in the usual manner.

In the accompanying drawings I have diagralnmatically illustrated my invention in connection with a sinY cylinder gas engine rovided with ordinary spark plugs of the.4 ]ump spark variety.

The engine is indicated generally at A and the s ark plugs at B, one terminal of each plug eing, as usual, grounded at the engine and the other terminal in circuit with the corres ending secondary C of the induction coils IIJ), by means of conductors C', the opposite terminals of which secondaries are grounded through the engine, as represented at E. The primaries D are connected, as by conductors j', with the respective terminals 1, 2, 3, 4, 5, 6 of a suitable timer, whose contact or arm 7 may be driven by the engine in usual manner, and is in electrical connection with the engine, as through conductorS. The opposite terminals of thc primaries, as 1, 2, 3, 4, 5, G, are connected as by wire 9 with the vibrator' or vibrating spring 10 having a contact point 11 adapted for engagement with a contact 12 shown carried by an adjusting screw 13 fitted to a bridge or support 14 in any well known manner. The armature- 10n of the vibrator 10 is shown of su'llic'ient area to co-act with the cores 15, 15n of an electro magnet having two windings 16, 16, one winding upon each of said cores, which windings are connected at their corresponding terminals a, l), and said windings are wound in opposite directions, and are of substantially the same number of turns andthe same gage wire. The conductor 9u connects with corresponding ends a of said windings rovide a relatively small con` and the conductor 9b connects with the opposite corresponding ends b of said windings and is grounded at the engine, and such clrcuit includes a battery 17 or any other suitable source of electrical energy. I have shown the cores 15, 15n substantially in the form of'a horseshoe or U-shape, whereby the two cores are connected together at correspending ends. The arrangement of said windings is such that the current will split or divide at the windings, passing substantially one half through each windln a north (pole is produced core an l responding end e another core,

and thereby at t c end ofone a south ele is produccdat the corwhereby tho I". oppositely windings i6, lua, due to the inake and break oi the magnet circuit by tne armature i0a or' vibrator il) l provide a suitable or relatively small condenser i8 which is bridged across the corrcsp ending terminals of tliewindings i6, 16a, as by being in circuit with tlie terininals c, l), as shown' by the wires 18a, we, connecting with conductors 9a, 9b. A suitable condenser i9 inay be bridged across the contacts il and 12 vin any well known manner, being slit-wn connected with conduct-or 9a at i9 and with the vibrator l) at 59".

By rneans oiE my improvements all of the primary induction coils will. operate accurately with respect to tlie time oi the closing ci" tlie corresponding circuit at tlie comuni-Y tator or tiniei', and material retardation by tbel vibrating rneclianisin is cause of the greatly reduced inductance and resistance at'the vibrator windings.
